> thousands of servers running just fine
Err yeah well you might have noticed these things called "laptops" and "desktops". SysVinit was... fine.. on servers. It worked badly on desktops and not really at all on laptops. I'm pretty sure the post introducing SystemD explained it all in detail if you want to learn something.
The issue with Linux on the desktop, and especially the laptop, in the pre-systemd days wasn’t the init system. It was the lack of quality drivers.
Now I’m not saying that systemd hasn’t brought improvements over sysv. But to say bash worked badly on laptops but fine on servers is just silly. That’s simply not how the technology works at all.
And I don’t need to read some promotional piece from Redhat to know this. I’ve been running Linux on desktops and laptops longer than many adults have been alive. So I’ve lived through these massive ecosystem changes and have a first hand account of life before systemd.
